Trial Summary

What is the purpose of this trial?

Randomized, post-market multi-center study investigating the efficacy of two sets of treatment algorithms in brain metastases (BM) patients at the time of first intervention for radiographic progression after stereotactic radiosurgery (SRS), with or without surgery.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have used bevacizumab within 4 weeks of starting the study. It's best to discuss your specific medications with the study team.

What data supports the effectiveness of this treatment for recurrent brain cancer?

Research shows that radiotherapy, including stereotactic radiosurgery and reirradiation, can improve survival and quality of life for patients with recurrent brain metastases, with minimal side effects. These treatments are effective in controlling local brain disease and are considered safe options for managing relapsing brain conditions. ^{1 2 3 4 5}

Is the combined therapy for recurrent brain cancer generally safe for humans?

Image-guided radiation therapy (IGRT) and intensity-modulated radiotherapy (IMRT) are generally considered safe, with some risk of side effects like gastrointestinal and genitourinary issues. The safety of these therapies has been a focus of research, and they are commonly used in clinical practice. ^{3 6 7 8 9}

How is the treatment of radiation therapy unique for recurrent brain cancer?

Radiation therapy for recurrent brain cancer is unique because it uses advanced techniques like stereotactic radiotherapy (SRT) and intensity-modulated radiation therapy (IMRT) to precisely target tumors, minimizing damage to healthy brain tissue. This approach allows for a second course of radiation, which is not standard, offering a potential option for patients with recurrent tumors. ^{3 10 11 12 13}

Treatment Details

Interventions

• Laser Interstitial Thermal Therapy (Procedure)
• Radiation Therapy (Radiation)
• Steroid Therapy (Corticosteroid)

Trial Overview The REMASTer trial compares two treatment strategies after initial SRS for brain metastases: Radiation Therapy versus Laser Interstitial Thermal Therapy combined with Steroid Therapy. It's randomized, meaning patients are put into groups by chance.

Radiotherapy and chemotherapy of brain metastases. Soffietti, R., Costanza, A., Laguzzi, E., et al.[2018]

Stereotactic radiosurgery is a commonly used and effective treatment for recurrent or progressive brain metastases, showing good results in local brain control and patient survival based on various clinical studies.

This treatment is considered relatively safe, with a low incidence of brain toxicity side effects, but further well-designed randomized studies are needed to refine patient selection and treatment guidelines.

Reirradiation for patients with brain metastases can effectively alleviate symptoms and improve survival rates, with minimal late neurotoxicity, making it a valuable treatment option that is often underutilized.

Recent studies indicate that stereotactic radiosurgery, in addition to traditional whole brain radiotherapy, offers promising results for reirradiation, enhancing treatment options for patients with recurrent brain metastases.

The phase II trial aims to evaluate the safety and feasibility of combining regional hyperthermia with moderately dose-escalated salvage radiotherapy for recurrent prostate cancer, focusing on minimizing severe adverse events.

If proven safe and feasible, this study could lead to a larger phase III trial to determine if adding hyperthermia improves treatment outcomes, specifically biochemical control of the cancer.

Despite aggressive treatments for brain tumors, recurrence remains common, and there is currently no standard care for managing recurrent tumors, making treatment challenging.

Advancements in radiation therapy techniques, such as IMRT and SRS, have improved tumor targeting and reduced damage to healthy brain tissue, but the benefits and risks of reirradiation for recurrent tumors are still debated, particularly regarding survival and toxicity.

The evolving role of reirradiation in the management of recurrent brain tumors. De Pietro, R., Zaccaro, L., Marampon, F., et al.[2023]

In a study of 33 patients with recurrent brain metastases treated with salvage stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT), local progression occurred in only 9.8% of brain metastases, indicating effective local control.

After 2 years, 37.7% of patients were alive, and 72% were free from distant brain failure, with no increase in toxicity or neurologically related deaths, suggesting that focal radiotherapy is a safe and effective option for managing limited brain metastases.

CyberKnife stereotactic radiotherapy (SRT) was found to be an effective treatment for recurrent glial tumors, with a median survival time of 22.3 months after recurrence among 37 patients studied over a follow-up period of up to 57 months.

The treatment showed no significant toxicity, indicating that SRT is a safe option, especially for high-grade tumors, which had a median survival of 29 months compared to 19 months for low-grade tumors.
